Under the revised Basel III Capital Regulations, what is the maximum limit for which banks can obtain fresh credit ratings from the specified CRA for bank loans?

Read the following passage and answer the following question (Q20 to Q21). The Reserve Bank of India (RBI), as part of its Basel III Capital Regulations, has allowed banks to use external credit ratings to assess their risk-weighted assets for capital adequacy purposes. However, restrictions apply to certain credit rating agencies, particularly in terms of new rating mandates and existing loans. For instance, there are specific limits on loan amounts for which fresh ratings can be obtained, and conditions governing the surveillance of existing ratings, particularly for larger working capital facilities. These regulatory changes aim to ensure that banks are using reliable and appropriate credit ratings to manage their capital adequacy in a risk-sensitive manner.
